SQL Security

The SQL SECURITY clause specifies the security context for executing other routines or inserting into other tables.

By default, a trigger applies the SQL Security property defined on its table (or — if the table doesn’t have the SQL Security property set — the database default), but it can be overridden by specifying it explicitly.

Note

If the SQL Security property is changed for the table, triggers that do not have an explicit SQL Security property will not see the effect of the change until the next time the trigger is loaded into the metadata cache.

See also SQL Security in chapter Security.

The Trigger Body

The trigger body is either a PSQL body, or an external UDR module body.

See The Module Body in the PSQL chapter for details.
